Hello
I am migrating to generate reports in a web-service and am having a strange problem that occurs sometimes, other times not, file is ok.
Apparently the Spire.XLS is keeping the file in use after closing, and the result is a corrupted file.
20 times reapeting same operation, at least about 5 this kind of problem occurs.
I'm using version 5.8.5.4.
I tried to migrate to the latest version which I am entitled, but there was another problem with special characters, as well as the problem of file in use also occurred.
What can I do?
